Al + Br2 → AlBr3 To balance the Br’s, make 3 Br2 and 2 AlBr3. Al + 3 Br2 → 2 AlBr3
To balance the equation, make 2 Al.
2 Al + 3 Br2 → 2 AlBr3 ...... if you would like more information please let me know and I can help you out
When a chemical reaction occurs, molecular bonds are broken and other bonds are formed to make different molecules. For example, the bonds of two water molecules are broken to form hydrogen and oxygen. Energy is always required to break a bond, which is known as bond energy.
